2-part polyurethane grout for heavy wheel load rail fixing (shore D 75)

Sika® Icosit® KC 330/10 is a flexible two-part polyurethane polymer resin grout. It is designed as a vibration absorbing, load-bearing, flexible grout for discrete or continuous trackwork baseplates where particularly high wheel loads are involved.

Heavy axle load main line vehicles and loading cranes.
Noise and vibration suppression.
Reduces erosion of concrete under baseplate.
More uniform load distribution into substructure.
Watertight undersealing.
Flexible and elastic (shore D 75).
Damping and compressible.
Good electrical insulation against stray currents.
No stress peaks on anchor bolts.
Good adhesion on various substrates.
Levels out tolerances.
Powerful, shear-resistant adhesive.
Absorbs dynamic stresses and prolongs the life of concrete substructure.
Long durability, less maintenance.

Usage

As a noise and vibration reducing grout under discrete baseplates or continuous embedded rails for high wheel loads (e.g. for heavy cranes, container gantry cranes, working pits and other similar applications).
As a flexible levelling layer for fixing heavy industrial machines to reduce vibration transmission.
